MARKING mncnmn.

Application filed April 17, 1922. Serial 1'l'o. ,080.

To all whom it may concern.

Be it known that I, FREDERICK OLSON, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Marking Machines, of which the following is a specification, reference being had to the accompanying drawing.

The invention relates to. a machine for marking articles, whether with the same mark or number or with-successive marks or numbers; the invention pertaining more particularly to means whereby the marking or numbering may be speedily and readily accomplished through foot actuated mechanism, whereby increased power is provided, while the hands of the operator are left free to manipulate or handle the article or articles on which the operation ,or marking is to be performed.

The invention also contemplates means whereby the marking mechanism or portion of the machine will automatically return to normal position, that is to say into a posi tion whereby the machine is in condition to not only release the article operated on, but also in condition to permit the insertion of a second or succeeding article, thus enabling the marking operation to be speedily carried on and accurately performed.

The objects and advantages of my invention will be more readily understood and comprehended from the detailed description of the drawing, wherein Figure 1 is a side elevation of my improved machine with portions cut away and partly shown in section. t

Figure 2 is a longitudinal sectional view taken onthe off-set line 22 of Figure 1 looking in the direction of thearrows.

Figure3 is a detail v1ew 1n perspective 7 of the plunger-operating lever.

Figure 4 1s a detail view in perspective of the lever-engaging cross-head or plunger attachment.

The specific embodiment of the invention as disclosed in the drawing comprises a plu-' rality of correlated numbering discs or wheels indicated at 10 in Figure 2, rotatably mounted on a suitable spindle or trunnion which in i turn is suitably mounted in a frame or yoke as at 11, in the well known manner heretofore employed. The numbering or marking mechanism includes a sultable inkl ng pad.

or element adapted to contact with the numbering or marking discs 01' wheels at a predetermined point and is arranged to move out of the path of the vertically reciprocating spindle or trunnion on which the marking or numbering discs or wheels are mounted, in order that the ink supplied portion of the numbering discs or. wheels may contact with the article which is intended to be numbered or marked. The trunnion-carrying frame or yoke is mounted to slide vertically in the main frame or head 12 which at its rear end is bolted or secured to the bed plate that the sprlng may exert upward pressure on the head or thimble 17 which tends to return the plunger with the numbering disc or wheel-carrying trunnion or spindle upwardly, namely back to normal position. The elements thus far described in a general way constitute elements associated and operating in a manner heretofore employed and therefore do not constitute my invention, so that a further detailed description of the marking or numberin elements, as well as of the trip lever 19, w erebythe numbering disc or wheels may be actuated, need not be entered into. I p I My invention, specifically stated, consists in mounting the bed-plate 13 on a suitable standard or support 20 which is preferably provided with a passage therethrough or made hollow throughout as shown in Figure 1, with the lower part enlarged or provided with a foot or base as at 21 to suitably sup port the machine. The lower portion of the standard 20 is cut away or providedwith an openingvat 22 for the passage of a footlever 23, the rear end whereof is pivotally mounted at 24 in one side of the base portion of the standard, while the free end is provided with a suit'ablefoot-rest or piece 25 which is shown pivotally or otherwise secured at 26 to the lever. The lever 23 is pivoted to swing v'ertically and at a point in proximity to the free or outer end thereof has a suitable spring 27 secured thereto, while oneend of the spring is secured at the point 28 to the standard 20. The spring is of sufficient power and strength to return the foot-lever 23 to its upward or normal position shown in Figure 1 when the foot of the operator is lifted The lever 23, at a point within the standard 20, is provided with a link or rod 29, which extends upwardly through a. suitable opening in the bed-plate 13 and also through a passage or opening in the skeleton head or frame 12 as shown in Figure 1. l

The head or main frame 12 is shown provided. with an upstanding portion as at 30, which is preferably bifurcated, to receive the end of lever 31 therebetween; the lever being pivotally mounted at the point 32 in any suitable manner to the main frame or head 30 to permit vertical movement of said lever. At an intermediate point lever 31 is shown provided with a hook member or screw-eye 33 whose threaded end receives a turn-buckle 3% whereby it is operatively connected to the rod 29; the connection permitting of proper adjustments in order that the levers 23 and 31 will not only move in unison, but both levers also permitted to reciprocate a degree sufficient to permit maximum operation of the plunger 16. The lever 31 is preferably of the construction shown more clearly in Figure 3, being provided with the bifurcated end 35 in Figure 3 which is adapted to straddle the head or thimble 17 of the plunger 16.

The threaded end of plunger 16 is provided with a cross-head as shown at 36 in Figure 4, which is preferably provided with a tapped aperture extending therethrough to receive the threaded end of the plunger; the radially disposed arms or portions 37 of the cross-head extending beyond the sides of the lunger and into the path of the immediate ends of the bifurcated portion 35 of lever 31, so as to permit said bifurcated end to rest thereon and have sliding engagement therewith during the oscillatory movements of lever 31. As is evident from the construction shown, the free end of lever 31 will be maintained in operative relation with the plunger 16 because the head or thimble of the latter passes between the bifurcated portion of the lever.

As is apparent from the construction shown, the marking or numbering mechanism of the machine will be brought into marking relation with the article inserted on the backing or block 14 of the bed-plate upon downward pressure being exerted by the foot of the operator on lever 23 against the action of spring 27. The downward pressure of foot-lever23 will cause lever 31, through the rod or link connections 29 -33 34, to exert downward pressure'on the crosshead 36 and thereby move plunger 16, with the elements carried thereby, downwardly in order that the inked portion of the marking or numbering discs or wheels will be brought into contact with the article.

The spring 27 will cause both the footlever 23 and the lever 31 to immediately return upward to normal position upon release of the foot pressure on lever 23 and thus allow the plunger 16 to move upwardly through the action of its spring 18, thereby causing the elements to move in unison. prefer to construct the machine as described, namely with the plunger 16 made returnable to normal position through the action of its own spring and with a loose or yielding operative relation between lever 31 and the plunger in order that no damage or injury may be caused to the marking or numbering elements and the carrying frame in the event of any slight displacement or jamming in the reciprocating frame portion which might interfere with and would prevent the immediate return upward to normal position, as the spring 18 is of less strength and tension than spring 27 and therefore not suflicient to exert so great an upward pull or pressure whereby breakage in the mechanism or the carrying frame thereof could occur; the lever 31, under such conditions being free to return or move upwardly to normal position independently of the marker controlling plunger 16.

My improved machine permits free use of both hands of the operator while at the same time providing a machine which is at all times under the control of the operator and made operable at his will; namely a construction which avoids the use of motive power which is apt to entail complications and which might result in serious injury and damage. It is apparent that the designating marks or numbers may be the same on succeeding articles, or successive numbers or marks for each article may be readily provided when desired.

I have shown what I believe to be the simplest and best embodiment of my invention; having described the same in terms employed merely as terms of description and not as terms of limitation, as structural modifications are possible and may be made without, however, departing from the spirit of my invention.

What I claim is 1. A machine of the character'described, comprising a standardhaving a main frame or head and a bed-plate mounted thereon, a lever fulcrumed at one end to said head, a marker carrying frame reciprocatingly mounted in said main frame or head and adapted to be engaged by the free' end of said lever, a foot lever pivotally mounted in the base of said support and having oper- 'tive relation with said first'mentioned lever to reciprocate the latter'aind therebyde'press the marker carrying frame, the operative relation between said 'first mentioned lever and the marker carrying frame being such as to permit independent movement of the first mentioned lever and the foot lever back to normal position.
